Handyman Villager

This villager repairs the entire village once any part of it gets destroyed. For example, if you need some quick wood, and you use a librarian's house, the Handyman will come over and place the corresponding number of wood blocks that you broke. This villager would be wearing a fully blue "plumber suit", and would trade the blocks that the houses are composed of. This villager would be in all villages. 

Trade examples:

Oak- Oak Logs, Oak wood planks, White Terracotta, Cobblestone, and Yellow or White beds.

Snowy Taiga(BE only) and Taiga- Spruce Logs, Spruce wood planks, Cobblestone, Spruce Trapdoors, Campfires, and Blue or Purple beds.

Desert- Sandstone, Cactus or Flowerpot Containing Cactus, Various Terracotta colors, and Blue or Green beds.

Savanna- Acacia Logs, Acacia wood planks, Acacia Wood, Terracotta, and Red, Yellow, or Orange beds.

Snowy- Spruce Logs, Spruce wood planks, Packed Ice, Snow Blocks, Lanterns, and Blue, Red, or White.

The Handyman Villager can either live in a small house like Nitwits, or a house specially designed for him like a shepherd's house.
